Oops, `make world' doesn't work as an upgrade mechanism from
3-STABLE to 4-STABLE :(.
Here is a possible way to upgrade via sources which should avoid the
pitfalls that I encountered.
1. First, bring your 3-STABLE system uptodate, if it already isn't so.
# cd /usr/src
# cvs -q update -PAd -rRELENG_3
# make world
# cd /usr/src/sys/i386/conf
# config YOURKERNEL
# cp YOURKERNEL /root # a backup
# cd ../../compile/YOURKERNEL
# make depend all install
# reboot
2. Checkout a 4-STABLE source tree
# mv /usr/src /usr/src-3X # (optional)
# cd /usr && cvs -q checkout -rRELENG_4 src
3. Do a `buildworld'
# script /var/tmp/make-buildworld make -DNOPERL buildworld
4. BEFORE the `installworld' step, you need to do a few things :(.
4a. Install a new version of `install-info'
# cd /usr/src/gnu/usr.bin/texinfo
# make install
`install-info' in 4-STABLE has a --defsection option that is
used in a number of places.
4b. Install a new version of `config'. This is needed for the next
steps.
# cd /usr/src/usr.sbin/config
# make install
4c. Apply the patch included in this mail. This patch is needed
because the 4-STABLE kernel sources rely on a feature not
present in 3-STABLE's GCC.
# cd /usr/src/sys/i386/i386
# patch < in_cksum_patch
4d. Build and install a new kernel
# cd /usr/src/sys/i386/conf
# cp GENERIC YOURKERNEL
# vi YOURKERNEL # edit to suit
# config -r YOURKERNEL
# cd ../../compile/YOURKERNEL
# make depend all install
4e. Save the contents of /bin to /bin.3X, just in case
# mkdir /bin.3X
# cp /bin/* /bin.3X
5. Reboot with the new 4.0 kernel. You need the new kernel because
the 4.0 versions of /bin/sh and other essential utilities use the
new sigaction system call (syscall #342) that is not present in a
3-STABLE kernel.
6. Complete the installworld. This should now hopefully complete.
# cd /usr/src
# script /var/tmp/make-installworld make -DNOPERL installworld
7. Run `mergemaster' and upgrade "/etc", etc.
8. Revert the change to /usr/src/sys/i386/i386/in_cksum.c.
From now on, the regular `make world' procedure should be sufficient to
keep uptodate.
